If the sec- 55 ondary folding followsan arrangement in ac-,

cordance with, for example, the primary folding, the secondary folding,when completed, will also present exposed margins for each section ofthe secondary folding. Therefore, as thus completed, the sectionsincident to the primary folding will each havean exposed margin which,for the sake of clearness, will be referred to as an index margin, andthen each section of the secondary folding which, of course, includesall the sections of the primary fold within the plane of the secondaryfold section, will have an exposed or index margin which is particularlyor peculiarly adapted to that secondary fold section.

Figures 4 to 8 may serve as a general example of the folding. If themain sheet (Fig. 4) is folded into the primary folds in the longitudinaldirection according to the method of folding, for example, shown inFigure 1 to thus provide the primary folds c, c, 0', etc., into thelongitudinal sections R, S, T, V, (Fig. 5) and the sheets so foldedreceive a further or secondary folding at right angles to the primaryfolds, for example, on the folding lines b, b, b", with each of suchsecondary folds at relatively different distances apart, one end of thesheet so folded will present relatively exposed free edges exactlysimilar to those resulting from the primary folds.

If desired and as preferred, each primary fol-d section, except the mainunderlying section, may

vbe cut through on every second secondary folding (line at b Fig. 4)which will, of course, divide the folds or sections of the primaryfolding from each other along the lines of each alternate line ofsecondary folding, so that the sheet as a whole is made up ofconnectedprimary fold sections which are each subjected to a single secondaryfold so that, when that particular secondary fold is opened out, (Fig.7) the sections included in that particular secondary folding arepresented flat in primary fold relation and preferably with theirmargins offset, so that any priopened out for inspection (Fig. 8).

mary fold of this secondary fold section may be Of course, the primaryfolds and also the secondary folds may be constructed in any number inaccordance with the size of the original sheet and with the desired sizeof the completed article after folding, the primary purpose of coursebeing to permit the sections of any one secondary fold to be opened outto provide independent access to the sections of the indexed primaryfold included therein.

As the sheet is folded longitudinally in secondary folding, that is thelines of secondary folds extend at right angles to the length of thesheet as resulting from the prjmary folds, it is apparent, that any twoor more secondary folds may be opened out to provide access toadditional lengths of primary folds. Furthermore, in this type offolding, convenient access to any primary fold .section on either facethereof is provided for,

thus permitting the sheet to be printed on both surfaces with anyselected material readily available without the necessity of opening upthe entire sheet.

The combined fold of this character provides a multiple character ofindex. As the exposed margin of each of the primary folds may be indexedor marked according to the character of showing on that fold and theexposed section resulting from each secondary fold may be appropriatelyindexed as to the character of showing on the respective primary foldsections included within that secondary fold, any particular portion ofthe showing printed on the sheet as a whole is not only convenientlyaccessible but is also conveniently marked or indexed to be readily anddefinitely selected with certainty and without loss of time.

The individual sheets may be printed in different colors or bethemselves of different color, or may be made of any material, evendifferent materials, or be made up of sheets having colored bands whichare parallel to or cross one another.

Any of the sheets, parts of the same, or the cover may be used to bearadditional plans or text such as advertisements, illustrations, etc.Cross reference over the parts of a map that has been separated by partcuts will be facilitated by the indexes.

What is claimed is:

l. A sheet of material having imprinted thereon a diagrammaticrepresentation such as a map, which is folded into a number of sectionsalong substantially parallel lines at a progressively increasingdistance from each other, the edges on one side of the folds registeringwith each other and folded again into a number of sections alongsubstantially parallel lines but transverse to the first set of parallellines, whereby sections with successively exposed edges parallel to eachset of fold lines are formed.

2. The device as claimed in claim 1 in which a fold line is out along aportion of its length whereby the sheet may be readily opened to display only a small section thereof.
